shaft 3 carries gear wheels 3 that are driven through suitablegearingfrom an electric motor 6 which is controlled as will he morefully described presently.

The receptacle 1 is provided with guides 7 within which are movable thesliding doors 8' and 9 prmidt with cooperating projections 10 and 11which insure closing the door 8 before-door 9 can be moved to its closedposition as will be seen from Fig. 1. The door 9 carries a camprojection 12 arranged to engage a switch rod 13 movable in .-i guide Handtcarrying the switch 15 which eoiipcrates with contact 11', of themotor circuit. The switch rot] 1'3 'alsri carries a handle 17 that ismovable in m:- slot. 18 'and arranged to engage alrecess 19 for apurpose that will presentlyuppcar more fully and it will be seenfroththis arrangement thatupon closing the doors 8 and 9 the switch 15is automatically closed and upon opening said doors, the switch isautomatically opened by the spring 20 althouglrit may be moved to closedposition when the doors are open, by operating handle 1T. 21 is amanually controlled switch button carrying switch 22 which cooperateswith contacts '23, and

The contacts 23 are also a part of the motorcircuit which will be described later. 2i is a switch rod provided witha switch 25 eoiiperating with contacts 26 and held normally in theosition shown in F i 4 by the spring 27. he switch rod 24" IS movable inthe guide 28 and is controlled by a'cam 29 which is mounted uponan'operating lever 30 journaled on the bearing 31 and having a handle32. The operating lever 30 has pivoted thereto a connecting rod33, thatleads to a link 3% fixed to a stub shaft 35, which is arranged in ahousing 36, as shown to 7 inclusive, and formin part of the brakemechanism that contros the motor (5.

rangeinent of electric circuits by which this result is aceomplished x yReferringto'Figs. Band 9, switches 15 they assume after the doorsare-closed and the apparatus. With "theparts in this pothe brake 1sreleased,preparatory to starting sit-ion, the'circnit is broketratswitch '22,. and

the motor can not be operated until the switch 22 is closed, this beingthe final operation in startingithe machine. 1 As soon as this is done,current passes from the main supply conductor-'18 through the'lineswitch 49 to conductor 50, thence throughlmagnetic coil 51, conductor52, switch 53, and cons ductdrs 54 and 551:0 the switchfw. The currentisthen carried throil' h'conductorhfi and switch 25 to' conductor 5 7 fromwhichit passes through switqlr22, as shown in dotted lines'in Fig. 9,and conductor 58 to switch 49, and-to the main supplycbhcluetbr "59.

The circuits leading to t afield and urinature of the motor involve nonovelty, and it is suflicient for the purposes of the present inventionthat-,the motor circuit s thus closed. At the same time, the magneticcoil 51 being energized causes a movement of a pivoted switch arm 60vwhich carries a series ofeontrolling switchestil, and also an arm 62that engages a'tail'pieee 63 upon switch 53, moving the nan to theposition shown in Fig. 9. througha resistance elcmentlhl. instead ofthrough conductor 54. In thoinit'ia'l' opera tion, full voltage isrequiredto energize the mag'netiocpil 51, so as to throw over the Thiscauses. the current to travel i switch arm 60, but after it. is oncemovcdgf to this position, the current-passing through resistance 64 willenergize the magnetic coil sufficiently to hold'th-switch -arin.60 inoperatin position. With the parts thus arrange as shown in Fig. 9, andafter switch 22 is released, the current travels from conshown in Fig.8, the motor is started by momentarily closing switch 22 andthe motorcircuit thereafter remains closed as long as switches-15 and 25 are heldin closed position. Upon the opening of either one of these switcheshowever, as by applying the brake mechanism or by openingcthe doors tothe receptacle, 'the motor circuit is immediately broken.

To start the apparatus the doors are closed movin tion. The b'rmechanism is released, moving -switch 25 to its closed position, afterwhich switch 22 is closedby the operator for a suflicient length of timeto energize the magnetic coil 51 and throw over the switch arm 60. Whenthe motor is stopped,

it is desirable that the container within the receptacle be brought to astandstill-ina certain relation with the receptacle so that the doors ofthe latter and thedoors of thecontainer are coincidently disposed. Forthis purpose iti's sometimes necessar that the container be given aslight additional movement after the receptacle doors-are opened. Thisisaccomplished in the resent a paratus by moving the handle I on sggitcrod 13 into engagement with the recess 19, which holds the switch 15closed,
